During NVM update, state machine gets into unrecoverable state because i40e_clean_adminq_subtask can get scheduled after the admin queue command but before other state variables are updated. This causes incorrect input to i40e_nvmupd_check_wait_event and state transitions don't happen. This issue existed before but surfaced after commit 373149fc ("i40e: Decrease the scope of rtnl lock") This fix adds locking around admin queue command and update of state variables so that adminq_subtask will have accurate information whenever it gets scheduled.
